7) If Pantry Sensor has trouble
Bad contact of connector/ insert correctly
Is MAIN PCB
Connector CN30 insert
correctly?
Is Pantry Sensor
normal?
Is the voltage between
MAIN PCB Connector CN30#8(Whiteblack)
to CN1#3(Black) normal?
Is the input voltage of IC01
MICOM Pin# 58 normal?
Start
NO
YES
YES
YES
YES
Replace temperature sensor
NO
Recheck the wiring connection
NO(0.6V > Measurement < 4.6V)
Check the iced-solder, solder
bridging, disturbed solder
NO
No trouble with PCB and temperature sensor.
Recheck the bad contact of the connection.
** Measuring point of resistance value according to

Pantry : CN30#8 #9 measuring resistance value
** 0 : Short trouble /
: Open trouble
Sensor MICOM/Connector number
Voltage measured between 4.6V ~ 0.6V.
Measuring voltage of IC01 MICOM #58,
